Author Affiliations +
In this paper, we present a stable dark soliton with its spectrum spanning about one octave generated in the silicon nitride microring resonator with normal dispersion. The dark soliton can be generated straightforwardly from noise. Then, we investigate the dependence of bandwidth and power level on pump power, the second-order dispersion, the ratio of coupling and intracavity loss coefficient and free spectral range.
